From 1970 through 1991, the United States led other OECD countries in overall labor productivity, a key measure of national competitiveness. During this period, labor productivity in these countries converged, both towards the mean OECD labor productivity and the U.S. level of labor productivity. This suggests living standards among the OECD countries are becoming more alike. In the latter half of the period, the rate of convergence slowed.
